Definitions
- the present invention relates to miniature receivers used in listening devices, such as hearing aids.
- the present invention relates to miniature receivers that have an improved coil-receiving section.
- a conventional listening device such as a hearing aid includes, among other things, a microphone, an amplifier, and a receiver.
- the microphone receives an acoustic signal (i.e., sound waves) from the surrounding environment and converts the acoustic signal into an electrical signal.
- the electrical signal is then processed (e.g., amplified) by the amplifier and provided to the receiver.
- the receiver converts the processed electrical signal back into an acoustic signal and subsequently broadcast the acoustic signal to the eardrum.
- the receiver 100 includes a housing 102 that protects the sensitive components mounted inside the receiver 100.
- the housing 102 may be of a size and shape that allows the receiver 100 to be used in miniature listening devices, such as hearing aids.
- an electromagnetic drive assembly 104 that converts electrical signals from a microphone into acoustic signals.
- the electromagnetic drive assembly 104 includes, among other things, an armature 108 and an electrically conductive coil 110 through which the electrical signals from the microphone pass. Lead wires (not visible here) from the coil 110 extend through an opening in the housing 102 and terminate at a terminal 111 (e.g., a solder bump) on the outside of the receiver 100.
- a magnet assembly 114 is also included in the electromagnetic drive assembly 104 adjacent to the coil 110.
- the magnet assembly 114 has a magnet housing composed of a pair of housing elements 116a and 116b.
- the housing elements 116a and 116b hold a pair of magnets (not visible here) that define a magnetic gap through which the working portion of the armature 108 extends.
- an electrical signal passing through the coil 110 induces a magnetic field around the armature 108. Variations in the electrical signal produces fluctuations in the magnetic field, causing the armature 108 to alternate between moving toward one or the other of the magnets.
- a diaphragm 118 converts the armature movements, via a drive pin (not visible here), into a corresponding acoustic signal that is then broadcast to the eardrum.
- the armature 108 is E-shaped, for example, with a base from which three parallel legs extend. Mounting of the armature 108 is such that the middle leg or reed of the armature passes through the center of the coil 110 along a central axis thereof, while the outer legs extend along the outside of the coil 110. The ends of the armature legs are then attached to the magnet assembly 114, which is adjacent to the coil 110.
- Coil formation typically involves winding a conductive wire around a coil former.
- a coil winding bobbin may also be used to form the coil.
- Epoxy is usually applied to the coil to prevent corrosion.
- the coil former or coil winding bobbin is then removed using tweezers or other similar instruments.
- tweezers For an example of a coil winding bobbin that is removed, see European patent EP1219135B1. Removal of the coil former or coil winding bobbin, however, often produces inadvertent contact between the tweezers and the coil. This contact may cause damage to the epoxy, which can result in corrosion of the coil.
- the armature 108 in the conventional receiver 100 is supported only at the ends of the legs where they are attached to the magnet assembly 114. The rest of the armature 108 is unsupported. As a result, large deflections may occur on the armature 108 when the receiver 100 is subjected to shock. A sufficiently severe shock may cause the armature 108 to deflect beyond the point of elastic deformation, thereby compromising the operation of the receiver 100.
- the present invention is directed to an improved receiver for use in listening devices, such as hearing aids.
- the receiver comprises an electromagnetic drive assembly that includes a bobbin having a coil of conductive wire formed thereon.
- the bobbin is capable of inhibiting the deflections on the armature that may be caused by shock.
- the bobbin is also capable of centering an armature leg within the coil.
- the receiver includes a magnet assembly, an armature having a moveable leg, and a coil assembly.
- the coil assembly includes a bobbin and a conductive wire wound around the bobbin.
- the coil assembly is adjacent to the magnet assembly and, together with the magnet assembly, defines a passage through which the moveable leg of the armature passes.
- the bobbin includes an inner surface defining the passage. The inner surface has at least one shock-absorbing structure for limiting a movement of the moveable leg within the passage when the receiver is subjected to shock.
- the receiver includes a magnet assembly, an armature having a moveable portion and a fixed portion, and a coil assembly.
- the coil assembly includes a bobbin and a conductive wire wound around the bobbin.
- the coil assembly is adjacent to the magnet assembly and, together with the magnet assembly, defines a passage through which the moveable leg passes.
- the bobbin includes an armature-mounting structure, usually in the form of slots in flanges of the bobbin.
- the moveable portion of the armature is substantially centered within the passage in response to the fixed portion being engaged to the armature-mounting structure.

- Figure 6 illustrates a cross-sectional view of a receiver having a shock-absorbing, armature-centering, and wire guiding bobbin according to yet another embodiment of the invention.
- Figure 7 illustrates a perspective view of an electromagnetic drive assembly according to embodiments of the invention.
- FIG. 2A a cutaway view of a receiver 200 according to embodiments of the invention is shown.
- the receiver 200 has many of the same components found in the receiver 100 of Figure 1, including a housing 202 that protects sensitive electronic components mounted inside the receiver 100.
- an electromagnetic drive assembly 204 that includes, among other things, a bobbin 206 and an armature 208 mounted on the bobbin 206.
- a coil 210 of conductive wire is wound around the bobbin 206 between a first flange 212a and a second flange 212b of the bobbin 206.
- the first and second flanges 212a and 212b serve as retainers for the coil 210 during formation thereof.
- a magnet assembly 214 is also included that comprises a pair of housing elements 216a and 216b.
- the housing elements 216a and 216b hold a pair of magnets (not visible here) that define a magnetic gap through which the working portion of the armature 208 extends.
- a diaphragm 218 converts the vibrations from the armature 208 via a drive pin (not visible here) into a corresponding acoustic signal that is then broadcast to the eardrum.
- FIG. 2B illustrates a cross-sectional view of the receiver 200 taken along the line A-A in Figure 2A.
- the armature is an E-shaped armature with three parallel legs 208a, 208b, and 208c.
- the outer armature legs 208a and 208c extend along an outside of the bobbin 206, while the middle armature leg 208b or reed extends through a center longitudinal axis of the bobbin 206 and also through the magnetic gap defined by the pair of magnets that are adjacent to the bobbin 206.
- E-shaped armature is used here, it is also possible to use other types of armatures (e.g., a single-leg armature or a U-shaped armature that has two legs) without departing from the scope of the invention.
- the bobbin 206 includes a coil-receiving portion 222 that is made of parallel coil-receiving members 222a and 222b, which connect the two flanges 212a and 212b together.
- the coil 210 is then formed by winding a conductive wire around the coil-receiving members 222a and 222b.
- the coil-receiving members 222a and 222b have respective inner surfaces 224a and 224b that, together with the coil 210, define a passageway in the bobbin 206 through which the middle armature leg 208b extends.
- the bobbin 206 is made of a material, such as liquid crystal polymer (LCP), which will not affect the electromagnetic field produced by the coil. Other materials that may be used include, for example, a polyamide/nylon material, such as Stanyl®.
- the inner surfaces 224a and 224b of the coil-receiving members 222a and 222b have one or more shock-absorbing structures 226a and 226b mounted thereon.
- the shock-absorbing structures 226a and 226b are preferably mounted substantially directly over the middle armature leg 208b on the respective inner surfaces 224a and 224b such that the structures can absorb any deflections that may occur on the middle armature leg 208b. In this way, the shock-absorbing structures 226a and 226b serve to limit the amount of deflection available to the middle armature leg 208b when the receiver 200 is subjected to shock.
- Locating the shock-absorbing structures 226a and 226b on the coil-receiving members 222a and 222b has the advantage of ease of manufacture. It is also possible to locate the shock-absorbing structures 226a and 226b on the magnets. In general, however, it is preferable to keep the shape of the magnets as simple as possible because magnets are often tumbled or barrel polished, which may influence or alter the dimensions of any shock-absorbing structures that are formed on the magnets. [30] In some embodiments, there is a slight gap between the middle armature leg 208b and each shock-absorbing structure 226a and 226b.
- the gap on one side of the middle armature leg 208b may or may not be the same size as the gap on the other side, depending on whether the middle armature leg 208b is centered or off-center within the bobbin 206. It is also possible to have no gap, i.e., the middle armature leg 208b is in direct contact with one or both of the shock-absorbing structures 226a and 226b so long as the structures are sufficiently elastic to allow the armature to perform its function.
- the shock-absorbing structures 226a and 226b may be made of any suitable shock-absorbing material.
- the shock-absorbing structures 226a and 226b may be made of an elastomeric material, such as a silicon based adhesive.
- the shock-absorbing structures 226a and 226b may be formed from drops of a cured adhesive.
- a cured adhesive is the UV-cured adhesive OG115 from Epoxy Technology, Inc. of Billerica, Massachusetts, with a Shore D hardness of approximately 86.
- the shock-absorbing structures 226a and 226b are integrally formed on the bobbin 206 and, thus, made from the same material as the bobbin 206.
- FIG. 3 illustrates a cross-sectional view of a receiver 300 having an electromagnetic drive assembly 304 according to embodiments of the invention.
- the electromagnetic drive assembly 304 is similar to the electromagnetic drive assembly 204 of Figures 2A-2B, except that it has a bobbin 306 which includes a substantially tubular coil-receiving portion 322.
- the result is that an inner surface 324 of the coil-receiving portion 322 alone defines the entire passageway in the bobbin 306. This is different from the previous embodiment in which the coil 210 and the coil-receiving members 222a and 222b together define the passageway.
- Such a coil-receiving portion 322 may also help improve the stiffness of the bobbin 306.
- Shock-absorbing structures 326a and 326b are then mounted on opposing sides of the inner surface 324 of the unitary coil-receiving portion 322 substantially directly over the middle armature leg 308b such that the structures can absorb the deflections that may occur on the armature leg.
- the bobbin may include an armature support structure that helps brace or stiffen the outer armature legs and also helps suppress the deflections that may occur on the armature legs.
- Figure 4 illustrates a cross-sectional view of a receiver 400 having an electromagnetic drive assembly 404 with an exemplary armature support structure on the bobbin.
- the electromagnetic drive assembly 404 is similar to the electromagnetic drive assembly 204 of Figures 2A-2B, except that it has a bobbin 406 which includes armature-mounting slots 428a and 428b.
- armature-mounting slots 428a and 428b are formed on the flanges 412a and 412b (only one shown in Figure 4) on the sides thereof that are substantially perpendicular to the plane of the armature (one slot on each side).
- the armature-mounting slots 428a and 428b are designed to receive at least a portion of the outer armature legs 408a and 408c and to provide bracing and stiffness support for the outer armature legs 408a and 408c.
- the size and shape of the armature-mounting slots 428a and 428b should be of a dimension such that at least a portion of each outer armature leg 408a and 408c can fit snugly in one of the armature-mounting slots 428a and 428b.
- the flanges 412a and 412b should have a width that is large enough to intersect at least a portion of the outer armature legs 408a and 408c.
- the support provided by the armature-mounting slots 428a and 428b also helps dampen the deflections that may be present on the outer armature legs 408a and 408c. Dampening of deflections may also take place on the middle armature leg 408b, although to a lesser degree. As a result, it may not be necessary to provide a separate set of shock-absorbing structures to compensate for deflection on the armature legs, although it is certainly possible to have both.
- the armature-mounting slots 428a and 428b also have the effect of automatically centering the middle armature leg 408b within the bobbin 406. The reason is because the engagement of the outer armature legs 408a and 408c in the armature-mounting slots 428a and 428b naturally forces the middle armature leg 408b to be located in a certain position. By selecting the proper placement for the armature-mounting slots 428a and 428b on the flanges 412a and 412b, the middle armature leg 408b can be automatically positioned in the center on the bobbin 406.
- the bobbin may include wire guides for guiding the lead wires of the coil that is formed on the bobbin.
- a receiver 500 having an electromagnetic drive assembly 504 with exemplary wire guides provided on the bobbin is shown.
- the electromagnetic drive assembly 504 is similar to the electromagnetic drive assembly 204 of Figures 2A-2B, except that it has a bobbin 506 which includes wire guides 530a-530d.
- the wire guides 530a-530d are formed as V-shaped grooves on one of the flanges 512a and 512b of the bobbin 506 and serve to guide the lead wires of the coil.
- wire guides 530a-530d there are four wire guides 530a-530d shown here, in practice, there may be more or fewer wire guides as needed, depending on the particular application. Also, the wire guides 530a-530d may be formed on one or on both flanges 512a and 512b, as needed. While a V-shaped groove is shown, other shape grooves may certainly be used, such as circular or rectangular grooves. Additionally, in some embodiments, a drop of adhesive may be placed in the grooves 530a-530d to help keep the lead wires in place on the flanges 512a and 512b.
- FIG. 6 illustrates a cross-sectional view of a receiver 600 in which the electromagnetic drive assembly 604 has all of the features discussed above with respect to Figures 2A-2B and 3-5.
- the electromagnetic drive assembly 604 is similar to the electromagnetic drive assembly 204 of Figures 2A-2B, except that it has a bobbin 606 which includes shock-absorbing structures 626a and 626b, armature-mounting slots 628a and 628b, and wire guides 630a-630d.
- a receiver 600 that may be more shock resistant (because of the shock-absorbing structures), is easier to manufacture (by virtue of the self-centering armature), as well as more reliable (due to less handing of the coil and wires, since the bobbin can be handled now during manufacturing).
- FIG. 7 illustrates a perspective view of the electromagnetic drive assembly 604 of Figure 6.
- the electromagnetic drive assembly 604 includes the E-shaped armature 608 engaged to the bobbin 606 (although any of the bobbins previously discussed may be used). As a result, the electromagnetic drive assembly 604 enjoys the benefit of being more resistant to shock, having a self-aligning armature, as well as making it easier to retain the lead wires.
- the electromagnetic drive assembly 604 further includes a magnet assembly 614 that is similar to the magnet assembly 214 of Figure 2A.
- the magnet assembly 614 is composed of magnet housings 616a and 616b, and magnets 620a and 620b that are housed within the magnet housing 616a and 616b.
- Outer armature legs 608a and 608c are then clamped between the magnet housing 616a and 616b.
- the coil assembly which includes the bobbin 606 and its coiled wire, and the magnet assembly 614 define a passageway through which the moveable middle leg 608b of the armature 608 passes.
- the magnet housing 616a and 616b help to position ( i . e ., balance) the armature 608 in the middle of the passageway of the coil and in the magnet gap between the magnets 620a and 620b.
- a drive pin 632 is connected to the armature 608 on one end and a diaphragm 618 (see Figure 6) on the other end.
- the coil receives a drive signal via lead wires 604a and 604b, the coil is energized in a manner that causes a known movement in the armature 608 and, thus, a known acoustic output from the diaphragm 618.
- Lead wires 604a and 604b are disposed in and retained by the V-shaped wire guides 630a-530b of the bobbin 606.
- Such an electromagnetic drive assembly 604 may be used in any miniature receiver of the type commonly employed in listening devices, such as hearing aids.
